CCDC now accepts structure factors

The Cambridge Crystallographic Data Centre (CCDC) is pleased to announce that structure factors are now being accepted with CIFs for deposition to the Cambridge Structural Database (CSD).

Colin Groom, Executive Director, commented that 'The CCDC supports the IUCr in highlighting the importance of retaining and validating experimental data. We strongly recommend that all journals publishing crystal structures should encourage their authors to provide these data in electronic CIF format.'

'The deposition of structure factors to the CSD is extremely welcome and will greatly facilitate the work of reviewers', said Sylvain Bernès, co-editor Acta Cryst. Section E. 'Archived structure factors also promise to be a rich source of data for research related to statistical bias in X-ray structures and in detection of systematic errors in data collections'.

CIFs and structure factors can now be deposited with the CCDC via our web-based deposition form at www.ccdc.cam.ac.uk/services/structure_deposit.
